Research Interests

My research activities lie in the field of experimental condensed matter physics. I am particularly interested the magnetic properties of materials such as transition metal oxides, organic magnets and magnetic nanoparticles. Measurements on these systems are carried out with a commercial QD MPMS magnetometer as well as a dc SQUID-based magnetometer developed in-house which is capable low field magnetometry at temperatures above 300 mK. Other instrumentation includes a 9GHZ ESR spectrometer operating between 100K and 550K and electrical transport systems for temperatures ranging from 2K to 1300K. I also use international facilities (ISIS, Paul Scherrer Institut, Institut Laue-Langevin) for other magnetic measurements.
